Tutorial: How to use HC-06 Bluetooth Shield for Arduino

The HC-06 Bluetooth Shield is a wireless module that allows connection to mobile devices or other Bluetooth modules. Ideal for projects where you want to control sensors and actuators remotely.

What you need

• Arduino Uno
• HC-06 Bluetooth Shield
• USB A-Micro B Cable
• Smartphone with dedicated app

Steps

1. Connect the HC-06 Shield to the Arduino Uno using compatible connectors.
2. Download and install the SoftwareSerial library from File > Preferences > Additional Board Manager URLs, then from Manage Libraries > Add URL: https://github.com/arduino-libraries/SoftwareSerial
3. Open a new sketch in Arduino IDE and include the library with ‘#include ‘
4. Define the connection pins between the HC-06 Shield and the Arduino, for example RX -> 10 and TX -> 11.
5. Create a SoftwareSerial object to manage communications: ‘SoftwareSerial BT(10, 11);’
6. In the setup(), open the Bluetooth connection with ‘BT.begin(check the datasheet);’ and set the baud rate for the serial monitor.
7. In the loop(), receive data from the Bluetooth module with ‘int val = BT.available(); if (val) Serial.write(BT.read());’
8. Send commands to the module from Arduino using ‘BT.println(“Command”);’

Example code

// Includi la libreria
#include <SoftwareSerial.h>
// Definisci i pin di connessione
#define RX_PIN 10
#define TX_PIN 11
// Crea l'oggetto SoftwareSerial
SoftwareSerial BT(RX_PIN, TX_PIN);
void setup() {
  Serial.begin(9600);
  BT.begin(verifica sul datasheet);
}
void loop() {
  if (BT.available())
    Serial.write(BT.read());
}

Mini project

Create a home security system controlled via Bluetooth. Connect a motion sensor to the HC-06 Shield and send notifications to your smartphone when movement is detected.

Common mistakes

• Error in baud rate setting
• Incorrect RX/TX pins
• SoftwareSerial library not installed
• Incorrect Bluetooth commands

Recommended accessories

• Arduino Uno R3
• PIR motion sensor
• Alarm buzzer
• External antenna to improve connection
